Colourism in Sri Lanka is still strong and alive

So there was this video made about Sri Lankans and why they tend to have darker skin and literally majority of the Sri Lankans in the comment section took offence to the video and started making very colourist and racist comments on how the video was made about Tamils and not a true representation of actual Sri Lankans who are Sinhalese. Like Sri Lanka is a country of all shades and colours and we still look down upon dark skinned people.
